Run accessibility check for a form

Generate a report of accessibility issues that should be addressed before deploying a form to production.

A form may have the following accessibility issues:

Tab order warnings: Controls that have a non-zero-tab order set, which creates confusing keyboard navigation patterns.
Image alt text: Images without meaningful alternative text attributes for screen readers.
Heading hierarchy: Missing headings or improper heading structure (skipped levels). At least one heading is required on the form.
Color contrast: Insufficient color contrast ratios (minimum 4.5:1 for normal text, 3:1 for large text). Only applies to hardcoded colors; theme colors are not validated.
Page title: Missing or non-descriptive page title element. A warning is shown if the page title uses the same value as the form name.
Input labels: Input controls without associated labels, which are essential for screen reader users.
Required fields: Warning if no required fields are marked on the form, which may indicate missing validation.
Icon-only buttons: Buttons that display only icons without text alternatives for accessibility.
Link text: Non-descriptive link text such as "click here" that doesn't clearly indicate the link's purpose or destination.

Procedure

Navigate to the forms list page.
Open the form to generate the accessibility check.

The form opens in the Design view, in a new browser tab.
On the form modeling bar, select the File tab and then select Accessibility check.

The system runs accessibility validation on the form and generates a report of any issues.
